BACKGROUND Field of Invention

The invention is in the field of computer networks and more specifically to a method, system and apparatus of a cellular network optimized protocol.

Background

The transmission control protocol (TCP) provides a core protocols of the Internet protocol suite (IP). Web browsers use TCP when they connect to servers on the World Wide Web, and it is used to deliver email and transfer files from one location to another.

Exemplary Methods and Systems

FIG. 1 illustrates an example process 100 for optimizing a cellular network protocol. In step 102, process 100 can provide a mobile device that is communicatively connected with a cellular network. In step 104, process 100 can periodically probe the current cellular network of the mobile device to determine the identity of the current cellular network. In step 106, process 100 can query an operating system of the mobile device to determine a current cellular network state. In step 108, process 100 can configure a data transmission using the cellular network optimized protocol based on a transmission speed of the current cellular network state. Additional information for implementing example embodiments of process 100 is provided infra.

FIG. 2 depicts a system 200 for Internet protocol optimization of cellular data network, according to some embodiments. Mobile device 202 can be a handheld and/or wearable computing device such as, inter alia, a smart phone, tablet computer, body-wearable computer (e.g. a ‘smart watch’, a head-mounted optical display system such as Google Glass®, a virtual reality head-mounted display device such as Oculus Rift® a handheld game console, a portable navigation system, etc.), a house-hold appliance, an internet of things device, etc. More generally, in some embodiments, any computing system that runs applications that communicate with the Internet 216 via a cellular or other wireless network 208 can operate in system 200 in lieu of mobile device 202. Application 204 (e.g. a ‘mobile application’, an ‘app’) can be application software designed to run in mobile device 202. System 200 can provide mobile device 202 with a unique identifier. The unique identifier can be used to identify mobile device 202 during a session in lieu of other identifiers such as, inter alia, IP address (see FIGS. 3 and 5 infra).

Cellular network 208 can be a radio network distributed over land areas served by at least one fixed-location transceiver (e.g. a base station). Cellular network 208 can communicate IP data packets between the Internet and mobile device 202 (e.g. as a cellular data network). Accordingly, mobile device 202 can communicate with an Internet-based entity via cellular network 208. Internet protocol (IP) gateway 210 can be an access point for Internet access from cellular network 208. IP gateway 210 can be a router or a proxy server that routes between cellular network 208 and such entities as IP optimization proxy server 212 and/or other Internet-based entities.

Application 204 can include client library module 206. Client library module 206 can convert (e.g. transparently transform) a TCP/HTTP request made by application 204 into a faster protocol optimized for propagation in a radio network such as cellular network 208. Client library module 206 can include a software development kit (SDK) provided by the cellular network optimized protocol system. It is noted that the conversion to the cellular network optimized protocol can be performed without making changes in a server associated with application 204. The conversion can be managed locally at the client-side of application 204.

The cellular network optimized protocol data packets can then be forwarded to IP optimization proxy server 212. As used herein, a proxy server can be a server that acts as an intermediary for requests from clients (e.g. application 204) seeking resources from other servers (e.g. destination server 218). Accordingly, IP optimization proxy server 212 receives the cellular network optimized protocol data packets. IP optimization proxy server 212 can then evaluate the incoming cellular network optimized protocol data packets and communicate with the destination server 218 (e.g. a google.com web server, an upstream server, a server that provides service to another server, a highest server in a server sequence hierarchy, etc.) of the original TCP/HTTP request. IP optimization proxy server 212 can request the service (e.g. a file, a connection, a web page, other web objects, etc.) designated by the original TCP/HTTP request from the destination server 218. IP optimization proxy server 212 can then serve the request response to application 204. In some embodiments, IP optimization proxy server 212 can also be utilized to push advertisements in the transmission to application 204. Advertisements can be germane to current content subject matter as detected by the IP optimization proxy server 212.

Data from past service requests can be stored in cache 214. Cache 214 can be a mechanism for the temporary storage (e.g. caching) of web documents, such as HTML pages and images. IP optimization proxy server 212 can also manage the settings of client library module 206 and/or a set of enterprise-managed mobile devices that include client library modules. For example, an administrator can enable/disable a particular client library module(s) with IP optimization proxy server 122 (e.g. with a dashboard functionality—not shown). In one example, enablement of client library module 206 can be tied to the identity of the user of the mobile device. In this way, a user of an enterprise's mobile device can log into an application 204 and automatically have client library module 206 enabled.

Administrators can also dynamically select a percentage of mobile devices in the enterprise's system that utilize the cellular network optimized protocol. For example, an administrator can select thirty percent (30%) of the mobile devices owned by her company to use the cellular network optimized protocol for communication in lieu of the TCP/HTTP protocol over a cellular network.

Access to use of the cellular network optimized protocol and elements of system 200 can be provided on a subscription fee basis. Subscriptions can be charged on a per monthly user basis. IP optimization proxy server 212 can include functionalities that collect and provide use information for subscription management and fees services.

It is noted that although the TCP/HTTP protocol is referred to throughout the document can be generalized to any TCP based protocol. For example, in some embodiments, the HTTPS can be used in lieu of and/or supplemental to the TCP/HTTP protocol. In some embodiments, any higher-level protocol running on a TCP-based protocol can be replaced by the cellular network optimized protocol for a speed enhancement. Additionally, while the cellular network optimized protocol is designed to be optimized for properties of cellular networks (e.g. high latencies and/or frequent packet drops etc.), it's not only the cellular networks that show these properties. A non-cellular example may be a heavily shared Wi-Fi network. Accordingly, the cellular network optimized protocol's methods and systems provided herein can be used to enhance other types of ‘sub-optimal networks’ and/or ‘slow, lossy networks’.

FIG. 3 illustrates an example process 300 for maintaining continuous sessions in cellular data networks, according to some embodiments. Process 300 can include the step 302 of providing a mobile-device identifier to a mobile device. The mobile-device identifier can uniquely identify the mobile device. In step 304, a session can be initiated between the mobile device and the IP proxy server. In step 306, it can be determined that the session suffers a lost signal. In step 308, a point when the lost signal occurred can be determined. Process 300 can include the step 310 of relocating the mobile device with the mobile-device identifier. The session can continue at the point the lost signal occurred. The mobile-device identifier can be applied at the proxy server level and/or at the conversion library module level.

In one example, some types of selected content can trigger utilization of the cellular network optimized protocol, while other types of content can still utilize a TCP/HTTP protocol. This type of filtering can also be implemented based on other factors such as time of day, location, and/or any combination of factors. FIG. 4 provides an example process 400 of content filtering, according to some embodiments. In step 402 of process 400, filtering instructions from a user and/or administrator are received for a particular mobile device. The filtering instructions can be applied at the proxy server level and/or at the conversion library module level. In step 404, the filter(s) are implemented with respect to the particular mobile device (e.g. based on the mobile device's unique identifier). In one example, a filter can be implemented at the conversion library module level to apply the cellular network optimized protocol for a specific type of media content (e.g. media content associated with a specific artist, website, genre, media content type, etc.). In another example, a filter can be applied to use the cellular network optimized protocol only during a specified time of day period. These examples are provided by way of instruction and not of limitation. Filters can be applied at the mobile device level and/or at the proxy server level.

It is noted that the request to the proxy server can be associated with an anonymized device identity. This can allow an administrator of the application to set in real time (e.g. assuming processing and networking latency) what percentage of users should have access to the cellular network optimized protocol and/or specific filters. These users can further be broken down into other subsets based on such factors as location, hierarchy in a corporation, historical use of application, etc. This option can also be used for testing purposes as well. A set of device identities can be prioritized (e.g. associated with important users). These prioritized identities can flag the conversion library module to always apply the cellular network optimized protocol regardless of other current filtering instructions.

The device identifier provided by the conversion library module can be used to provide uninterrupted downloading of files to an application in a mobile device even when the mobile device undergoes an IP address change (e.g. when the mobile device changes a location and couples with a new Wi-Fi network, etc.). FIG. 5 depicts an example process 500 of session continuation when the session undergoes a temporary break, according to some embodiments. Mobile device can include a mobile-device identifier 502 used in a session 506 with a proxy server 504. Session 506 can suffer a lost signal 508. Rather than creating a new session, a continued session 510 can be implemented as the unique mobile-device identifier 502 can enable the proxy server 504 to continue at the point the lost signal 508 occurred. The unique mobile-device identifier 502 can be an alpha-numeric string.

The cellular network optimized protocol can implement a secure connection without the two round trips required in an HTTPS protocol. For example, a data transfer between a mobile device and a proxy server can be secured via a public key stored on the mobile device. For example, the cellular network optimized protocol public key can be stored in the conversion library module (e.g. by embedding a public key in the SDK). When a first request comes from the conversion library module, a secure session can be implemented. The conversion library module can provide the data that is signed and encrypted with the public key. The proxy server can have a private key to decode public key. It is noted that communication from the proxy to the destination server can be implemented with the HTTPS protocol.

Additional example attributes of a cellular network optimized protocol are now provided. The cellular network optimized protocol may not directly utilize a Domain Name System (DNS) server. The cellular network optimized protocol may not an implement a TCP handshake process. The cellular network optimized protocol can implement a more efficient bandwidth probing process. For example, a TCP/HTTP protocol may implement a bandwidth probing technique to obtain an accurate network measurement. In contrast, the conversion library module can query an operating system of the mobile device to determine a current mobile network state (e.g. 2G, 3G, etc.) as the mobile device is periodically probing its current cellular network. Accordingly, the data transmissions using the cellular network optimized protocol need not perform separate bandwidth probing technique (e.g. TCP slow-start probing). Data transmissions using the cellular network optimized protocol can be set based on the transmission speed of the known current cellular network state.

The cellular network optimized protocol can implement a smarter backoff algorithm. A backoff algorithm can be used to space out repeated retransmissions of the same block of data. For example, when a data packet is dropped in a TCP protocol transmission, the TCP/HTTP protocol may restart by again implementing the bandwidth probing process. The cellular network optimized protocol can avoid this conservative TCP/HTTP ‘backoff’ technique and maintain the higher speed of the currently available cellular network.

Additional Systems and Architecture

FIG. 6 is a block diagram of a sample computing environment 600 that can be utilized to implement various embodiments. The system 600 further illustrates a system that includes one or more client(s) 602. The client(s) 602 can be hardware and/or software (e.g., threads, processes, computing devices). The system 600 also includes one or more server(s) 604. The server(s) 604 can also be hardware and/or software (e.g., threads, processes, computing devices). One possible communication between a client 602 and a server 604 may be in the form of a data packet adapted to be transmitted between two or more computer processes. The system 600 includes a communication framework 610 that can be employed to facilitate communications between the client(s) 602 and the server(s) 604. The client(s) 602 are connected to one or more client data store(s) 606 that can be employed to store information local to the client(s) 602. Similarly, the server(s) 604 are connected to one or more server data store(s) 608 that can be employed to store information local to the server(s) 604.

FIG. 7 depicts an exemplary computing system 700 that can be configured to perform any one of the processes provided herein. In this context, computing system 700 may include, for example, a processor, memory, storage, and I/O devices (e.g., monitor, keyboard, disk drive, Internet connection, etc.). However, computing system 700 may include circuitry or other specialized hardware for carrying out some or all aspects of the processes. In some operational settings, computing system 700 may be configured as a system that includes one or more units, each of which is configured to carry out some aspects of the processes either in software, hardware, or some combination thereof.

FIG. 7 depicts computing system 700 with a number of components that may be used to perform any of the processes described herein. The main system 702 includes a motherboard 704 having an I/O section 706, one or more central processing units (CPU) 708, and a memory section 710, which may have a flash memory card 712 related to it. The I/O section 706 can be connected to a display 714, a keyboard and/or other user input (not shown), a disk storage unit 716, and a media drive unit 718. The media drive unit 718 can read/write a computer-readable medium 720, which can contain programs 722 and/or data. Computing system 700 can include a web browser. Moreover, it is noted that computing system 700 can be configured to include additional systems in order to fulfill various functionalities. Computing system 700 can communicate with other computing devices based on various computer communication protocols such a Wi-Fi, Bluetooth® (and/or other standards for exchanging data over short distances includes those using short-wavelength radio transmissions), USB, Ethernet, cellular, an ultrasonic local area communication protocol, etc.

In one example, a computerized-system can include a mobile device comprising at least one computer processor, a memory and a network interface. An application implemented by the at least one computer processor of the mobile device creates a unique identifier. The unique identifier is stored in the memory of the mobile device. The unique identifier acts as a permanent address for sending packets from a proxy server to the mobile application. A current internet protocol (IP) address of the mobile device is only used as a temporary forwarding address for a packet. A proxy server that detects when the IP address of the mobile device changes via a communication of the change from the application. The proxy server continues sending a remaining data of a download session to a newly acquired IP address without having to restart the download session from scratch.

Message by Message Tunability of Message Reliability in a Cellular Network

FIG. 8 illustrates an example process 800 for message by message tunability of message reliability in a cellular network, according to some embodiments. Process 800 can provide message by message tunability of message reliability between n-nodes (e.g. a mobile device, a server, another user-side computing device, etc.) to n-other nodes. In step 802, an intermediate networking service for messaging can be provided between different nodes of a network (e.g. data-communication network, a mobile network, content delivery network, etc.). The tuned message can originate from a user's computing device and be delivered to a group of nodes. The group of nodes can be the computing devices of a group of players in an online game room.

In step 804, process 800 can periodically probe a current cellular network of a mobile device to determine an identity of the current cellular network. In step 806, process 800 can query an operating system of the mobile device to determine a state of the cellular network. In step 808, process 800 can configure a data transmission using an optimized protocol of the cellular network based on a transmission speed of the state of the cellular network.

Various reliability modes can be discussed. Reliability and in-order modes can be provided. These modes are tunable (e.g. not just in a purely reliable mode) in steps 804 and 806. Tunablity can based on the various numbers to data packets and/or messages. Tunablity can based on global sequencing vs. local sequencing as well.

In one example, a flexibly reliable protocol and API can be provided. This can allow the networking system to implement a synchronizing call into an SDK (e.g. as provided in client library module 206, etc.). The synchronizing call can instruct that the message be sent to receiving nodes a reliable fashion with a deadline (e.g. 500 ms). If the deadline is not met, then the networking system drops the message. In another reliability mode, the application utilizing process 800 can have the application call the relevant code to deliver the message to best of ability w/out reliability (e.g. a best effort mode that uses less bandwidth, etc.). In another reliability mode, process 800 can impose complete reliability. In this mode, process 800 can deliver the message regardless of the time to arrival (e.g. or with a relatively longer waiting time).

Process 800 can use a flag that provides ordering among messages. For example, process 800 can tune a sequence of messages for a hard deadline of 500 ms and to deliver only the message in a specified order (e.g. based on a global or local sequence number of the message). If the messages fall out of order, then process 800 can cause only the lower sequence numbered messages to be delivered and drop higher/out of order sequenced messages.

In one example, one client can send multiple messages can be sent to n clients in a group of clients (e.g. wen n clients are messaging each other or addressing a single other client). Accordingly, a sequence of messages can be between each destination and source. For example, if a source A is sending to source B there is a unique sequencing of messages between A and B while there is a global sequence number the relevant server that is managing the networking of the messages. This global sequence number can be maintained for all messages going through the networking system.

Process 800 can implement the various techniques of FIG. 1-7 to optimize message delivery as well (e.g. maintain session continuity across breaks, provide the reliability protocol, etc.).
